Hello, ill start by saying that i've searched and seen similar threads with this problem but no situation matches my case completely so i've created this thread.
Before I explain here are my specs:
i7-930 Bloomfield 2.8Ghz
ASUS P6T-Deluxe V2
8GB DDR3 HyperX Kingston
GeForce GTX 570 1.4GB
LC Power 6650 V2.3 (NEW)
500GB HDD Western Digital
So whenever I started playing SOME games my PC would "force restart" for example: Battlefield 4, Team Fortress 2, Splinter Cell: Blacklist while on others it would run without any problems (Assassins Creed 4 and almost any older game).
I would get the usual blackscreen so there's no BSOD. I have checked almost all components of my rig and tested them. Benchmark test on CPU and GPU, replacing GPU with older (GTX 275, which works fine with the other rig), memory test with memtest86 returned no errors, checked all connectors, replaced old power supply (LC Power 6600 V2.2), reinstalled Windows 7.
Now since I expect some people are going to blame it on the PSU and bash the LC Power brand I should say that this system worked flawlessly with my old LC Power 600W PSU for about 2 years. The problems started about 20 days ago when my PC would SHUT DOWN during gaming. Since then I bought a new PSU thinking that was the problem and it still wouldnt work on all games, but then the system started restarting. However since I got a new LC Power 650W only Battlefield 4 would work for some reason, that is, until a couple of days ago when it started restarting almost instantly after loading screen.
This really puzzles me as I cannot be sure if its the PSU or the motherboard, which are probably the only two suspects left. So if anyone has any suggestions to what the problem could be i'd really appreciate it.
Thank you.
